Yes, it was within the confidence interval of 500 years. They should
have been the same though as I didn't change the 67 marker haplotypes.
I thought maybe the Generations2.xls file on your website may not be the
latest?

I ran a set of 67 marker J2a1* pre-J2a1h haplotypes through your MRCA
age estimator (I had 31 of them) and the age came out as 218.6053
generations ago or 6558.2 years ago (6600 +/- ??? years ago). The
mismatch in this group was wider, up to 23 mismatches out of 67 markers,
than the J1 Cohen's. The J2a1* pre-J2a1h are determined using a J2
clade predictor like Whit's Bayesian Haplogroup predictor. J2a1*
pre-J2a1h consists of two main groups which I call simply alpha & beta.
J2a1* pre-J2a1h-beta is mostly Jewish (not entirely, just mostly) and it
_contains_ a Cohen cluster. I used your MRCA age estimator on this
group too (there were 21 haplotypes with 67 markers) and arrived at an
age of 135.7287 generations ago or using 30 years per generation,
4071.861 years ago (4100 +/- ??? years ago). Note that the age of the
MRCA of this cluster (J2a1* pre-J2a1h-beta ) is not the same as the
Cohen cluster contained within --- I made no attempt to isolate Cohen's
specifically. I just used the pre-J2a1h-beta clade that I have developed
using my own J2 clade predictor program (consisting of Cohen's and
non-Jews).

I'm working on a J1 clade predictor program mainly to split out the J1
Cohen cluster from J1. I should have this done in a few days. This
program should help me split off (hopefully) a large group of J1
Cohen's. This group will be based on the set of 66 J1 Cohen haplotypes
discussed previously. However this group will contain (probably) many
non-Jewish haplotypes. We'll see ...

Also Ken, I tried your Generations2 again on the 37 marker J1 Cohen's
and it did not work. I checked that the data was lined up properly. I
didn't see any problems. Please recheck with the last file I sent for
37 markers.
